To get rid of \( h \) on the left side of the equation \( h - 3 = 9h + 9 \), you should subtract \( h \) from both sides. This will help to isolate the \( h \) terms on the right side.
Here’s how it would look:
Starting with: \[ h - 3 = 9h + 9 \]
If you subtract \( h \) from both sides: \[ h - h - 3 = 9h - h + 9 \]
This simplifies to: \[ -3 = 8h + 9 \]
Now you have isolated the \( h \) terms on the right side of the equation.
